One problem related to exterior rearview mirror has been reported for the 1999 Chevrolet Suburban. The most recently reported issues are listed below.
My new surburban and several of those that I looked at have windshield visual distortions. Example: vehicles looks taller and skinnier or shorter and wider than they are. It has a number of these optical ripples. The distortion, like a carnival house of mirrors, makes me dizzy and confuses speed judgements--vehicles suddenly seems bigger and closer, or smaller and farther away. Outside left hand rearview mirror likewise has ripple effect. This is ridiculous.
